.mp4 not showing in Mocha AE

.MTS converted to .MP4 in Premiere pro cc latest.

The .MP4 file does not show in Mocha AE.

What can be done?

 

btw I did not find a search function, is there one?

This is usually caused by a format mocha can't read, or a codec mocha isn't compatible with.
There are certain types of codecs and file types that mocha does not support, usually native, unprocessed codecs off of cameras and AVIs on Windows. You may need to convert the file to something mocha supports, such as quicktime or AVI with a basic codec or an image sequence. If your screen is black or white for clips but not for images, it is most likely the codec for the movie files that is causing the issue.
Keep in mind the Codec is not the same thing as the file type, it sounds like you have a codec problem with the compression you are using for your MP4, like ProRes or something similar. A codec is the type of compression, the file type is AVI or MOV.

Other troubleshooting tips (because this sounds like it may be a driver or installed codec issue instead of a format issue):
  • Double-check that your quicktime drivers, codecs, and video card drivers are up to date, and that quicktime can open the file. (The most likely cause to these formats you listed not working is probably that the codecs need to be updated on your machine).
  • Try changing your codec to a more widespread codec. Usually any other quicktime format like animation, h.264, or JPEG compression should work, or another type of common .AVI compression.
  • If the footage loads in quicktime but not in mocha, try converting the clip to a file we know for sure that mocha recognizes, like a TIFF or JPEG sequence, to test and make sure that mocha is running properly.
mocha supports most standard movie clip and image sequence formats. In order to use clips (ie. not image sequences) you must have QuickTime installed. Level of QuickTime support can vary depending on the operating system.
What to Do if mocha Does Not Support Your Footage
In the event that you are working in a format that mocha doesn't support, we recommend converting the footage to an image sequence.
If you are just tracking, you can use any compressed format such as a JPG sequence and then use your original footage when you apply the data. If you are going to be doing rendering, such as using Mocha Pro’s remove or insert modules, then we recommend converting to a DPX or TIFF sequence.
Make sure of the following when converting to an image sequence:
  • The frame rate, aspect ratio and dimensions are the same as the original footage.
  • If you are creating proxy footage, make sure the aspect ratio and frame rate are the same.
  • If you are using a particular bit depth, make sure you convert to the same depth if you are using the footage for rendering inside mocha
  • If using compressed footage, don’t set the compression too low, as this will create artifacts that may hinder tracking and roto.
  • Make sure mocha supports the sequence you are converting to!
  • If you would prefer to convert to a movie clip format then we recommend a standard format that QuickTime would understand, such as Animation.
With mocha V5 though, we have an upgradable plugin option for release that may fix this issue altogether.
